The REL mode applies to all measurement functions except frequency and duty
cycle. It subtracts a stored value from the present measurement value and displays
the result.
For instance, if the stored value is 20.0V and the present measurement value is
22.0V, the reading would be 2.0V. If a new measurement value is equal to the stored
value then display 0.0V.
